Sgs Pro 14675 SJ-1 Cone Carbide Bur 1/4 in Shank

Product Description

The SGS PRO 14675 is a single-cut tungsten carbide abrasive bur in the SJ-1 cone profile, designed for precision material removal and deburring in metalworking applications. It features a 1/4-inch shank diameter and an overall length of 2.0 inches, with a cutting diameter of 0.25 inches and a length of cut of 3/16 inches. The 60-degree included angle of the cone geometry makes it well suited for countersinking, chamfering, and contour work in tight areas. Rated to 55,000 RPM, this bur is built for use in high-speed die grinders and rotary tools used across machining, fabrication, and maintenance trades.

This bur is intended for use on a broad range of ferrous and non-ferrous materials, including steel, hardened steel, stainless steel, cast iron, titanium, cermet, nickel, copper, and copper alloys. It is a practical choice for machinists, toolmakers, welders, and maintenance technicians who need consistent cutting performance on both production and repair work. The SJ-1 cone profile is a standard industry specification, making this a direct-fit replacement for worn or broken burs of the same designation in existing tooling setups.

Key Features

• SJ-1 industry-specification cone profile with 60-degree included angle
• Tungsten carbide head construction for extended tool life on hard materials
• Single-cut tooth style for smooth finishing and efficient chip clearance
• Rated to 55,000 RPM for use with high-speed die grinders and rotary tools
• Uncoated head for direct carbide-to-material contact
• 1/4-inch shank fits standard collets on most die grinder models

Compatibility

Compatible with steel, hardened steel, stainless steel, cast iron, titanium, cermet, nickel, copper, and copper alloys. Fits any die grinder or rotary tool accepting a 1/4-inch shank collet.

Installation Notes

This bur is installed and operated by machinists, toolmakers, and fabricators using die grinders or rotary tools. Before mounting, ensure the tool is fully powered off and the collet is clean and properly sized for a 1/4-inch shank. Do not exceed the rated 55,000 RPM maximum speed for the bur. Secure the shank firmly in the collet and inspect the bur for any chips or cracks before each use.
